whats the best one to get for a cattman y pipe?

 

Just get a universal 1 from AutoZone etc. and have an exhaust shop weld it in.

 

i would call brian and see what he suggests, it is his product after all. Maybe he'll sell you one for cheap

 

ya ive done that. waiting for his reply. thanks guys

 

I have talked to Brian about this problem. I have the same problem (became unavoidably obvious when i replaced my new cat and cat-back and took a look at the inside of it ) and he expected the flex section to be a 10" by 2 1/2" or 2 1/4". I expect to get a double layer and get it installed soon. Hoping the exhaust shop can weld it in fairly easily?

 

bringing up a fairly old thread... but is it o.k to get a bigger flex sextion than the one supplied for headers??? i have the 3.0 OBX headers and i need to replace mines, the flex section is very small about 6.5 maybe 7" im trying to use a 2.5X8 or X10

 

Go to Summit/Jegs/Vibrant Performance....I would suggest Vibrant over the others since they do offer one that's inner lined for heavy duty turbo service requirements! I curious what kind of cat or catback systems you guys are running that caused your Ypipe flex sections to fail? I sold mine (Cattman Ypipe VQ35) earlier this year and it still looked new inside and out!

 

You live in Texas...the people with flex sections that are breaking (myself included) are probably mostly up north.

 

Those are Cattman's that are failing? About how old is our Ypipe? It is T-304 Stainless Steel...

 

mines just never worked from when i got it... i've never really had one failing on me

 

Bad motor mounts would probably tear it apart over time.
